Check out some of the Asus laptops. They are affordable and usually built for light gaming. Otherwise, a Dell xps i hear are pretty nice for a bit more money. Just some ideas...

Another thing you might want to consider if you are planning on gaming with it is the screen quality. For example, when i play WoW on my toshiba (only 6 months old), even at 60fps it will sometimes appear choppy due to my screens slow refresh rates.
